I am 65 and face the real prospect of gigging again. Unfortunately, we have no roadies. I will be lugging my own equip. Have an Ibanez SDGR 500 that I love. One of the lighter basses around. Looking for a lite amp that will easily fill a medium room. My back and shoulders just cringe at lugging a heavy bass amp. Always felt a 15" speaker was a must but I'm willing to listen to reason. Thanks for any suggestions gang!
